EMERGENCY VOLTAGE CONTROLLER WITH TEMPERATURE COMPENSATION Russian patent published in 2003 - IPC

FIELD: car equipment. SUBSTANCE: emergency voltage controller includes generator with excitation winding which first and second output terminals are connected through ammeter and storage battery which minus terminal is connected to common bus. Third output terminal of generator is connected through excitation winding of generator to its fourth output terminal and is connected through ignition switch and ammeter to plus terminal of storage battery and through first trimming resistor to first terminal of control winding of first hermetically sealed reed relay. Controller also has second hermetically sealed reed relay, first winding controlling second hermetically sealed reed relay which first terminal is connected through capacitor to common bus connected in series with first hermetically sealed reed relay and voltage controller. In addition it incorporates second trimming resistor, second winding controlling second hermetically sealed reed relay connected in series. Second terminal of second winding controlling hermetically sealed reed relay is connected to common bus and first terminal of second hermetically sealed reed relay. First terminal of second trimming resistor and second terminal of second hermetically sealed reed relay are correspondingly connected to third and fourth terminals of generator. Fourth terminal of generator is connected to first terminal of first winding controlling first hermetically sealed reed relay, second terminal of first hermetically sealed reed relay is connected to output terminal of voltage controller and second terminal of winding controlling first hermetically sealed reed relay is connected to common bus. Controller has first and second switching-off windings acting correspondingly on contacts of first and second hermetically sealed reed relays and connected with their first terminals through second pair of contacts of ignition switch to first lead of generator and with their second terminals to common bus. Controller is supplemented with additional winding controlling second hermetically sealed reed relay, bimetal switch and additional winding controlling first hermetically sealed reed relay. Additional winding controlling first and second hermetically sealed reed relays are connected in parallel and in series with bimetal switch and are placed in parallel with winding controlling second hermetically sealed reed relay. EFFECT: widened functional potential of controller. 1 dwg
